 conclusion, the existence t)f" Ph. Fnigaruimtri fDC ) iSchroet. in Japan, although

REMARKS:— Our plant corresponds exactly in every respect to the specimens 

 of Ph. amcnccmum (Pk.) Diet, and there remains but little doubt as to tiieir iden- 

 tity. The ])resent species is more or less closely related to Fh. yezoensi, u. sp , Ph. 

 fusiforme Schroet. and Ph. Po.mc-iaiiltißorae Diet. But from Ph. yezocnse n. sp. it 

 diifers in form of papilla, the size of warts and also the number of cells. From 

 Ph. fmiforme Schroet. the number of cells and the foi ni of the upj)ermosL cell 

 appear to warrant sufficient disagreement. Ph. Po.sae-multißorae Diet, again varies 

 from this sjiecies in respect of the color and fbi-m of pedicel and the numb^^r of 

 cells. 



F. vox TlIl'MEX (26) recorded the occurrence of Ph. i:iiibüorficiHin Schrank.) 

 Wint. u[)on J'om dahurica. But the species in question, though parasitic on the 

 same ho.-^t plant, sufficiently proves beyond doubt its identity to Ph. (uit.rk'antuii 

 (Pk J Diet, rather tiian to Fh. .^i(bcor/i<-iii)ii. 'Schrank j Wint
